Background

About Peter Leinberg

I design and deliver cyber exercises that don’t just test systems—they strengthen them. With deep experience in planning, developing, and facilitating cyber resilience exercises across critical sectors—including nuclear, health, and infrastructure—I help organizations move beyond compliance to true preparedness. My work bridges the gap between technical threat scenarios and real-world crisis response, enabling leaders to rehearse for the risks that matter most. Whether running tabletop simulations for executive teams, coordinating multi-agency national-level exercises, or building cyber-physical threat scenarios, I bring a structured yet creative approach grounded in realism, strategic outcomes, and measurable improvement. My passion lies in equipping organizations to respond with clarity, coordinate under pressure, and recover with speed. Let’s connect if you’re developing cyber resilience programs, looking to run your first exercise—or want to pressure-test your crisis comms, decision-making, or incident response protocols.
